Definitions

• Pile Fibre / Wear Layer – Tufts of solution dyed, Nylon 6 yarns made from recycled Nylon 6 from both post industrial and post consumer sources. The post consumer portion is from reclaimed carpet and fishing nets. The source of the reclaimed carpet is Interface’s extensive ReEntry® 2.0 carpet reclamation program.

• Carrier – nonwoven tufting primary, a polyester fabric, into which the wear layer is tufted. • Backing (Precoat) – a latex coating which bonds the tufts into the carrier • Stabilization (Fibreglass ) – a nonwoven fibreglass fabric embedded in the structural backing which provides

dimensional stability. • Structural Backing (GlasBac®RE) - a recycled layer of post consumer polyvinyl chloride (vinyl) that gives

structure and dimensional stability to the modular carpet and is bonded to the wear layer with a vinyl bond coat.

Standard. Delivery and Installation of the Floor Covering

Delivery

The product is most commonly transported by truck. For the life cycle assessment, a 34-40 tonne truck with 85% utilization of its payload and an average transportation of 805 kilometers to the place of installation is assumed.

Installation

Installation of this product does not require adhesive application, but is done using TacTiles® preventing damage to the subfloor, increasing ease of removal and recycling, and installation during occupancy. If TacTiles® are not used, the recommended installation adhesive is InterTac, a water based acrylic. For full installation instructions, see the Interface Installation Guide.

According to ISO 14025

Health, Safety, and Environmental Aspects During In stallation

The VOCs associated with traditional flooring adhesives are avoided for both the installers and the building occupants by TacTile® installation method. Carpet tile does not require a foam cushion underlayment used in traditional broadloom carpet installations. The TacTile® method creates a floating floor, preventing damage to the subfloor and simplifying removal at end of life.

Waste

Waste is minimized by the modular aspect of the carpet tile. While installation waste can be sent to landfill or incineration, the preferred method is recycling through Interface’s ReEntry® 2.0 take back program by contacting the local Interface Country Business Manager.

Packaging

Carpet tiles are packaged in recycled cardboard boxes (93% post consumer recycled content cardboard). Packaging waste should be recycled through local cardboard recycling.

Use Stage

The product is warranted for a service life of 15 years of heavy use. However carpets are often replaced before their service life expires due to fashion.

Life Cycle Assessment

General

A total Life Cycle Assessment was completed in accordance with ISO 14040 / ISO 14044. Life Cycle Stages assessed:

• Production Stage • Installation Stage • Use Stage • End of Life Stage

Page 11: Recycled Nylon 6 Styles - Adobeinterfaceinc.scene7.com/is/content/InterfaceInc... · Recycled Nylon 6 Styles . According to ISO 14025. This declaration is an environmental product

Figure 5. Life cycle stages diagram

Description of the Declared or Functional Unit

One square meter of installed modular carpet for heavy use. The use stage is considered for one year of service life. The reference flow is one square meter of modular carpet.

Cut-off Criteria

The cut-off criteria established for the study include or exclude materials, energy and emissions data. For the purposes of this study, the criteria are as follows:

• Mass – If a flow is less than 1% of the mass of the modelled product it may be excluded, providing its environmental relevance is not a concern.

• Energy – If a flow is less than 1% of the cumulative energy of the model it may be excluded, providing its environmental relevance is not a concern.

• Environmental relevance – If a flow meets the above criteria for exclusion, yet is thought to potentially have a significant environmental impact, it will be included.

The total excluded flows do not exceed 5% of overall life cycle.

Allocation

Where relevant, the background data incorporates some allocation as in the power mix, where possible appropriate geographical grid mixes were used. No upstream impacts were allocated to recycled materials. End of life burdens of recycled materials were allocated to the input of those materials in the production stage.

Background Data

GaBi 5 software system was used for modeling the life cycle of the modular carpet.

Data Quality

For the data used in this LCA, the data quality is considered to be “good to high” quality. The definition of this quality range stems from the following descriptions. The data and data sets cover all relevant process steps and technologies over the supply chain of the represented carpet products. The LCIs from the GaBi 5 database and Plastics Europe are mainly based on industry data and are completed, where necessary, by secondary data. The operations data is representative of a sufficient sampling over and adequate period of time. The temporal correlation falls under a three year window for the vast majority of data considered. The geographical correlation is slightly challenging as there is very little life cycle information available that is country specific in every facet. For Interface, there is a reliance on data produced from European sources with country specific considerations during the LCI creation. Given that the data is from similar production conditions and representative of the technology and production paths used by Interface’s direct suppliers, this is acceptable to Interface and deemed to have an appropriate level of quality. A possible source of uncertainty from geographical sources is the incorporation of European electricity grid mixes into many of the LCIs that are used.

System Boundaries

The Life Cycle Assessment includes all relevant cradle-to-grave environmental information for one square meter of carpet. The system boundaries include raw material production and processing, carpet manufacturing, energy production, packaging, transportation, carpet installation, use and maintenance, as well as the end-of-life options (recycling, incineration or landfill disposal).

Notes on the Use Stage:

The warranted service life of the product is 15 years. The use stage includes both vacuuming and extraction cleaning according to the maintenance guidelines of the Carpet & Rug Institute and accounts for the electricity, water, and cleaning agents consumed. The use stage impacts have been annualised.

Results of the Assessment

The LCA results are documented separately for the stages: • Production Stage • Installation Stage • Use Stage

Interpretation

The majority of the environmental impacts occur during the extraction of raw materials and processing included in the Production Stage. In most carpet, products the major contributor to life cycle impacts is the Nylon in the yarn. Because this product is made with very high recycled content, the Nylon, while still a contributor to Global Warming Potential (32%) is comparable to the contribution by the backing materials (26%). Because no wet dyeing processes are used in solution dyed yarn, the processing energy in the Production Stage is lower than in some carpets, but is a minor contributor to the total GWP (7%).

According to ISO 14025

The LCA included installation byTacTiles®, but the impacts would be higher if traditional adhesive method was used. Installation has minimal impact due to the modular nature of carpet tile and the innovative installation method, TacTiles®. Modular carpet tile allows for lower installation waste (2%) as compared to the waste in a broadloom installation. Modular carpet also eliminates the need for cushion underlayment, another contributor to waste and impact in broadloom carpet installations. The TacTile® installation method uses small connectors which attach the carpet tiles to each other, creating a floating floor. This eliminates the need for spread adhesive and all of the wastes and VOC emissions associated with wet adhesive application. In addition to ease of installation, the TacTile® technology also supports recycling making carpet removal easier and resulting in returned carpet clean of adhesives improving recyclability.

The Use Stage is represented in this report for one year of maintenance. The contribution to the life cycle impact is small because carpet requires only regular vacuuming and intermittent extraction cleaning.

End of Life Stage for these products is represented as landfill and it accounts for 4% of the GWP, but every effort is made to insure the product is returned to Interface for recycling. The ReEntry® 2.0 carpet reclamation program is an extensive reclamation and recycling program that recovers both yarns and backings from post consumer and post industrial carpet.

Interface and its stakeholders share a common concern for the environment with particular interest in mitigating climate change through the elimination of product-related emissions. They have addressed this concern by creating climate neutral products. The total GHG emissions created during the life cycle of the products (raw material acquisition, manufacturing, transportation, 7 year use and maintenance, and end-of-life disposition) are modeled using Life Cycle Assessment methodology. These emissions are then neutralized through the purchase and retirement of an equivalent number of verified emission reduction credits. As a result of this program, the GlasBac® N6 products represented by this EPD can be made climate neutral by customer request. This program is verified by SGS.
